Volume is the quantity of three-dimensional space enclosed by a closed surface. For example, the space that a substance or 3D shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.

What does the word volume mean in math?

In math, volume is the amount of space in a certain 3D object. For instance, a fish tank has 3 feet in length, 1 foot in width and two feet in height. To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet.

What we mean by volume?

(Entry 1 of 3) 1 : the degree of loudness or the intensity of a sound also : loudness. 2 : the amount of space occupied by a three-dimensional object as measured in cubic units (such as quarts or liters) : cubic capacity — see Metric System Table, Weights and Measures Table.
